I had a dashboard that was working. I added a field to the BAQ, added some View Rules to some grid views. Got the message. Removed the rules and changed the BAQ removing the added field. As far as I can tell this is identical to my original version but I am getting the above message when "Testing" through application builder.

Any ideas?
